- This statistical technique involves both normal and abnormal controls and
graphically helps to differentiate between systematic and random errors.
The square repr/- 3 standard deviations for both controls. Red circle
represents SQR(SD1
2 + SD2 2 ) = 2. The two median lines (vertical and horizon-
tal axis) represent zero error normal and abnormal controls, respectively. The
intersection of both median lines is called the Manhattan Median. The dia-
gonal through the Manhattan Medial is the ideal location, high correlation
position for the pairs. Points near the line but outside the 2SD circle indicate
a systematic error. Points that lie far from the 45-degree reference line indi-
cate a random error.
